Abstract:

In this article characteristics of willow and topinambour stems used for energy generation are presented. The potential of energy plants grown in Lithuania is reviewed, the methods of plant converting to energy are presented, and different chopping mechanisms are reviewed. The article presents a methodology for evaluation of willow and topinambour stems, their bio-metrical properties and physical-mechanical properties of stem chaff. The experiment results were discussed. Experiments were made on manually cut willow and topinambour stems, which were chopped by drum, disc and screw type choppers. Bio-metrical properties of non-chopped willows and topinambour stems were determined, and the stem chaff physical-mechanical properties such as moisture content, density, angles of natural crumble and fall were evaluated and the investigation of chaff thinness was fulfilled.
